Invoice Match vs the three-way match already in your ERP
Most ERPs can tick PO, GRN, and invoice against each other. The queue still fills because capture is noisy, exceptions have no pack, and the match does not know the number should-cost put on the contract. DiscvrAI matches on that trail, routes only genuine exceptions, and leaves payment release with a human.
Side by side
| Dimension | ERP native three-way match | DiscvrAI |
|---|---|---|
| Who owns the number | The PO price, whether or not it is the awarded contract rate | The contract number should-cost and sourcing set, then PO/GRN/invoice against it |
| What gets matched | Three documents, if all three posted cleanly | PO, GRN, and invoice plus evidence for the miss: duplicate, tolerance, policy, short receipt |
| Exception handling | A shared inbox of mismatches with no confidence score | Only genuine exceptions reach a human, with the pack already assembled |
| Human gate | Payment still waits on someone reconstructing the trail | A human still releases payment. The agent does not auto-pay |
| ERP | The AP module is the match engine and the queue | Reads the documents you already post. ERP stays the book of record |
| Proof model | Match rate on a sample of last month's invoices | Shadow against your own historical PO/GRN/invoice set before anything auto-posts |
Keep the ERP. Stop treating a three-way tick as the whole of accounts payable. Invoice Match enforces the number the contract actually awarded, with evidence on every miss, and a person still at payment.
Common questions
No. Invoice Match reads PO, GRN, and invoice from the ERP you already run. Your AP module stays the book. The agent adds evidence, exception triage, and a trail a listed-company audit can open.
No. Capture gets the fields in. Matching decides whether those fields agree with the PO, the GRN, and the contracted rate. OCR without match is a faster inbox.
No. A human still releases payment. Low-confidence matches never auto-post.
Should-cost sets the number used in the award. Invoice Match flags any bill that drifts from that number. Same vendor, same item, one trail.
A slice of historical POs, GRNs, and invoices, plus the tolerance rules you already use. CSV exports are enough for an assessment. You see match accuracy in shadow before go-live.
